This rule (not new though) came as a 'she can't be serious' to the kids. But, what's the difference between TV and DVD. Well, if they are watching the TV, they have to choose their favourite programmes to watch whereas for DVD, they have free access to the DVDs and they can watch as many times as they want.
Moreover, some of the DVDs are not 'child-friendly' and are not suitable for Wyng's viewing. Of course, it's always the Qo Qo ie Hoe who masterminds the whole thing and turns on the DVD player without Mummy's prior approval.
So, the ultimate thing to do is to ban DVD on weekdays to their annoyance.
Guys, there are discipline and rules at home.
